The 2024 Ford Maverick has a single fuse for the telematics unit that you can remove without throwing a code or an error. No idea if this remained true after the 2025-2026 refresh, but worth knowing.

> Even after the modem is removed, if you connect your phone to the car via Bluetooth then the car will use your phone as an internet connection and send all the same telemetry data back to Toyota. However, if you use a wired USB connection then it does not do that (see the discussion here and elsewhere), so I exclusively use CarPlay via USB.

The problem with this is that both carplay and android auto capture their own vehicle telemetry. So even though the car is not able to use your phone as a general data pipe, Google and Apple still get access to this data when you're connected.

They are both very cagey with how they talk about this (or don't).

> Unfortunately I think it’s only a matter of time before the modem and GPS become more deeply integrated into the car (making this blog post infeasible), or cars have more drastic failure modes when the modem/GPS is removed, or anti-right-to-repair laws get passed to further clamp down on this behavior.

Guaranteed

What is the suspected method of Bluetooth communication?

Afaik phones do not share their internet blindly to Bluetooth devices.

Maybe two metal pins through the GPS and the cellular antenna coaxial cables would do the trick?

Great guide! After getting to the end, I had no idea what AirPlay was so I looked it up... bro, all this effort to avoid telemetry and you are using an iPhone XD
